Ethyl P-Cresylcarbonate
INCI: ETHYL P-CRESYLCARBONATE
Ethyl P-Cresylcarbonate is a synthetic fragrance ingredient that adds a sweet, floral scent to products, but it offers no skincare benefits and may cause sensitivity in some individuals.
In plain English
Ethyl P-Cresylcarbonate is a lab-made chemical that smells pleasant—often described as sweet or floral. It is added to cosmetics and skincare products solely to improve their scent. It does not moisturize, treat, or protect the skin in any way. Because it is a fragrance ingredient, it can sometimes cause irritation or allergic reactions, especially in people with sensitive skin.

Research notes
Limited peer-reviewed research specifically on Ethyl P-Cresylcarbonate. Its safety is inferred from broader studies on fragrance ingredients and regulatory assessments by bodies like IFRA and the Research Institute for Fragrance Materials (RIFM).
Common label clues
- Typical concentration
- Typically used at very low levels, often below 1% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets, subject to IFRA guidelines on safe concentration levels.
- Common uses
- Fragranced products, Perfumes, Body lotions, Cleansers
- Environmental note
- As a synthetic compound, its environmental persistence and bioaccumulation potential are not well-studied, but typical low usage levels suggest minimal impact.
Good to know
- Fragrance ingredients like Ethyl P-Cresylcarbonate are often listed simply as 'fragrance' or 'parfum' on labels, so it may not appear by name.
- Regulatory bodies like the International Fragrance Association (IFRA) set usage limits to minimize sensitization risks.
